Microdetermination of dulcin by colorimetry was devised. The color developed by the modified Jorissen reaction, on addition of a small amount of glacial acetic acid, turns into a violet solution (λmax 550mμ). By measuring the optical density of this solution at 550mμ, 30-360γ of dulcin in 1cc. of the solution can be determined. This method was found to be comparatively specific to dulcin.
